staging: vc04: Convert vchiq_log_warning() to use dynamic debug

Browse Source 
Move vchiq_log_warning() custom logging wrapper based on printk to use
dynamic debug. The log category is dictated by vchiq_log_category
which will become the part of the warning string format that will be
logged to dynamic debug (for grep).

All the vchiq_log_warning() calls are adjusted to use the
modified wrapper.

While at that, remove the extraneous "----" from few of the
warning string text.
